In a crockpot, combine the cooked chicken, frozen corn, diced onion, diced potatoes, and minced garlic.
Pour in the chicken broth and stir to combine all ingredients.
Add the dried thyme, paprika, salt, and pepper. Stir well.
Dot the mixture with butter. Cover the crockpot and cook on low for 6-8 hours or on high for 3-4 hours.
About 30 minutes before serving, stir in the heavy cream. Adjust seasoning if needed.
Once the chowder is heated through and the potatoes are tender, ladle into bowls and garnish with chopped parsley if desired.
